Ford F-150 (2009-2014) :: Truck Will Rev No More Than Three Times Then Idle For About 10 Seconds
Sep 12, 2017
2009 F-150 Lariat 4x4 with 5.4L.
My truck will rev no more than three times then idle for about 10 seconds. Then rev 3 times then idle for about 10 seconds. It keeps doing this. For weeks. Idles about 500, revs to 1500. The dealer had it in the shop for 3 days and found nothing wrong with it. I have a video but it won't let me upload it. I don't know what I can do since the DEALERSHIP doesn't even know what to do. Doesn't throw a code.

I have notice maybe a dozen times in the last few weeks that my 2013 5.0 Screw downshifts at odd times. It usually occurs while coasting around 35-40 mph (in 4th gear and downshifts to 2nd gear) or around 50 mph (in 5th gear and downshifts to 3rd gear). Obviously when this occurs, the rpms jump and when I get into the gas, the truck takes a few seconds to accelerate because it first must shift into the next higher gear. What is causing this?

I am having a strange issue with my truck. It is a f150 2009 xlt ext cab 4x4 5.4 liter
For the past 2 weeks I've had this light thump about 1 or 2 seconds after the truck starts driving,not really annoying but it kinda got me wondering
Since last week it makes a weird scraping noise from the rear end when coming to a stop (10-0 kmh) it doesn't do it all the time though
For a couple days now it makes this terrible squeaking/scratching/whatever(very loud) noise from the rear end when i accelerate from a dead stop, the one time when i crossed a highway, last night when i backed out of a parking spot (again not all the time).
Also when driving through a parking lot,hitting a few bumps and dips I can hear a rattling noise coming from underneath the truck.
Transfer case due for replacement? I don't know what this could be.....

I have a 2010 F150 5.4 with 43k miles. When approaching traffic lights or making a turn and you are approaching idle speeds the truck will start to stall out then ultimately shut off, causing me to loose all functions. It has cause my wife to almost get into a couple of major crashes. Sometimes when trying to start it back up it acts like it is not getting any gas it just keeps turning over. I took it in and it could not be diagnosed because they could not duplicate the problem. This will happen for a couple of days and then be fine for a month or two then start right back at it.

I didn't pick up the Raptor--passed on it for other reasons. I still have my 2010 that I bought with an extended warranty--I'm too old to play with them anymore and rather have everything covered.
When I bought my truck it was a factory certified pre-own so I got the 100k warranty plus an extended bumper-bumper coverage.
With that said I have the 5.4L engine and I've noticed here recently that's it is quite sluggish at times. I've read and most say put a tuner on it--in the past I would be all over that. My old 6L Diesel had a tuner but of course during that time I was all for blowing up engines and replacing them. Now not so much.
I noticed that the previous owner threw a damn Airaid intake on it -- I feel like the Airaid is really screwing crap up. I'm wondering if I should just buy the pieces I need to go back to a stock airbox?

I am looking at 2013 FX4 with the 5.0 that has 127,000 miles. Truck is pretty clean cosmetically except for the inside of the bed which is pretty rough. When I went to look at the truck I was curious to hear it on initial start up and it was really quiet. I have never heard in person the dreaded knock of the 5.0, only on youtube. After the truck idled for 10min while we talked I did kinda start to hear a little deep but very light thwump, thwump, thwump but it would fade at times and you wouldn't hear anything. I never heard it while I drove the truck. I know there are prob millions of these motors out there and the internet may make it seem worse than it is but would it scare you to buy a 2013 with 127K? I had thought originally that the 2011-2012 were the years with the problems but the latest 5.0 knock thread has me wondering.

I have a 2001 Ford F150 Lariat. It has the 5.4L Triton motor. I was having starting problems as such the truck would crank and not start or crank, start and barely idle and stall within 5 seconds. It was NOT tripping any lights. I was told it was a possible fuel issue. I have since changed the fuel pump, fuel filter, as well as the hoses in the rear connected to the tank. Truck started, ran great, even seemed to have more power. Ran great for about a week. I was on my way out yesterday about 2 miles from home when the truck just stalled out on me. It is now having the same issues it was having before I changed the pump, filter, etc. What the issue may be? Clogged line? Fuel injector? If it is an injector how can I tell which one?

I got a 2010 F-150 and just installed RECON headlights and taillights on my truck yesterday. Today, I went to go and use my remote start and the lights come on like it should and then it beeps 3 times and doesn't start. All my doors are closed. I thought maybe it was something with my hood sensor but I couldn't really find it.

Have a 2009 Ford F-150 with 5.4 ... Recently installed a cold air intake and now when I start it burns black smoke for maybe 15-60 seconds.
I have to rev the engine up by pushing on the gas or else it will stall.... after the 15-60 seconds the smoke turns clear and it idles with no problem and sounds normal.
This happens every time I don't use it for over 9 hours or so if I leave it for a couple hours it will start normal and idle normal....

My 2010 F150 Lariat Supercrew stated this beep yesterday. Every 15 seconds I get one beep. It seems to be coming from the radio, and the louder the radio is, the louder the beep. Even with the radio off, I can still hear it.
I've done lots of searches on this topic, but they all seem to be related to an airbag system issue, where there are 5 beeps in a row. Mine is just one short beep every 15 seconds. Can't find anything in the owners manual about this either.

I have a 2011 F250 with the 6.2 gas engine. I have been having a problem that the dealership says there is nothing they can do and have never heard about.
After the truck sits all night I get in and drive it for 10-15 min. It gets warm and I get out turning it off. When I come back about 15-45 min later I start it up and go to leave. As I pull out and start to accelerate in first gear the truck goes to an idle for about 2-3 seconds. I push the gas pedal and get no response. After a couple of seconds it picks up wherever you have the gas pedal. If you have the pedal to the floor it jumps you forward. This is not putting on any lights and the computer is not throwing any codes. According to the dealership the computer is telling them there is nothing wrong.
This has happened 12 times in the past 6 months. It has happened since I bought the truck. I have just started documenting it as of 6 months ago. It is not something I can make it do on command. After it happens once it doesn't seem to do it again for a week or two. I have 31000 miles on the truck. The dealership has had it for 4 days now and can't seem to get it to happen for them.

I'm having some strange action in the turn where sometimes it "sticks" and also I sometimes get a loud whining sound for 10 seconds or so and I believe it's coming from the power steering but I could be wrong.
I know my ecoboost has an electronic power steering system but that's the extent of my knowledge on it. Does it have a pump anywhere in the system that could be making this whining noise?
124,+++ miles, no real issues, runs like a champ.

Have a 2011 F150 with the 5.0. 91K miles. On startup-cold or warm-there is a ticking/tapping noise coming from the engine for about 3-5 seconds then it goes away. Happens on every single start. Sound like it's coming from driver side on top of engine, but hard to pin point.

I want to lower my 2014 FX2 supercrew 2/4. Can't seem to find any drop spindles for it. What are you using to drop your trucks. I don't want to change the driving or handling of the truck any more than necessary.

So my truck hit 1,000 miles. I decided to change the oil to get the factory oil out and remove any material that may be in there from the break in. I know the motor hasn't fully broken in. My question is what is the purpose of that shroud under the front of the truck? It seems like it can almost get caught on parking bumpers. It also makes it very difficult to get under there and change the oil. I had to go from the side. Need to remove it? It seems to be held by 2 good size bolts by the frame.

I'm having a problem with my 2010 F150 4x4. I'm a mail carrier and when I'm stopped at mail boxes my truck flutters and and acts like it's not getting gas or not getting fire. If I give it gas it goes on. It may do this 1 time a day or 100 times a day. My check engine light has come on and then after awhile it will go off. The Ford dealership thinks it is an oil pressure problem but the oil pressure gauge doesn't drop when this happens.

My wife and mom went to the dealership today to get remote start installed on their F-150's (bad decision not to do it from the factory). Both trucks had it installed, and it starts the truck fine, but the problem is as soon as they put the key in the ignition to turn it to "Run", the truck shuts off and they have to restart it. The tech says thats "Normal", and it's because of the "My Key" feature.
Neither of the trucks have had any of the keys set up to be "My Keys", all are exactly how they are from the factory. Something doesn't seem right....

I have pulled a pop up with my truck before with no problem. I bought a boat on Friday and pulled it too and from the lake ( 2.5 hours each way). The boat is 21 feet and weighs 3000 pounds empty, no gas. The trailer is a bumper pull. I was pulling no more then 4,000. Under 50 mph everything felt fine. At times when going over 50 the truck was shaking. It would happen and then stop. It does not seem to be coming from the engine.
It would happen up hill and down hill. I was thinking it was just the vibration from the boat, can a load that size make the whole truck shake?? Also the truck made a horrible clunk after backing the boat down the ramp and pulling it back up. It happened when I took the truck out of park into drive. This can be something other then the transmission???

So today was the hottest day I've encountered, since purchasing my '13, FX4, EcoBoost. It was 91 degrees out, which I know isn't THAT hot for some parts of the country.
That said, it's the first time since I've owned my '13, EcoBoost that I needed to use A/C all day. One thing I noticed is that the A/C fans are EXTREMELY loud.
The noise outside seems louder than an early 6.0 Powerstroke idling, or say even the 7.3 PSD. Sounds like a 747 taking off.
Is this normal or is something wrong with my truck? If I turn the A/C off, the super loud fan turns off, and the low speed fan for what I assume is the radiator keeps on, but is barely heard.
I don't remember the A/C fan being that loud on my previous truck '11, 5.0, XLT, but it had more equipment, and the engine wasn't as quiet as my EcoBoost now, which is almost silent.
